IMPROVEMENT IN SASH-LIFTERS.

Specification forming part of Letters Patent No. 141,647, dated August12, 1873; application filed March 31, 1873.

To all whom it may concern:

Be it known that I, HIRAlVI KINGSBURY, of Rochester, in the county ofMonroe and State of New York, have invented certain Improvements inWindow-Sash Lifters, of which the following is a specification Thisinvention consists in the employment of a circular metallic socket withturned-down flanges to be let into the face of window-sash opposite theputty side, and there secured by a screw or otherwise, and to be used aslifters for such sash.

Figure l is an elevation of a section of ordinary window-sash having oneof my lifters attached. Fig. 2 is a transverse section of the same online 00.

People occupying houses provided with the modern style of Windows withlarge lights, each sash containing but one, or at most two lights, haveall experienced the annoyance of opening the window by lowering thgpppersa s h onofrmfitlY lowejrfolf Knobs are sometimes applied to theloweFsH-h of such v windows for this purpose, but they cannot be to theupper ones. The object of my invention is to provide a remedyrfor thisdifficulty, and

one which shall be equ tbllyl applicahlwtoth sashes, an dlye ornamen a-aswell as useful.

Tlre'lfier or socket 0 may be cast, but it is preferably formed by adrop from sheet metal. A hole is bored in the face of the sash with abit made for the purpose,iso that the socket shall more accurately fitin the hole so bored. The socket may be secured in position by a screwor other suitable means, or it may be formed and applied as shown inFig. 2, the head resting upon the face of the sash as such projection isslight, it would not interfere with the action of either the upper orlower sash. In the employment of this latter construction of the liftersthe bit with which the sash is bored may be provided with a creasing-tool, if desired, by which an annular crease may be formed for thereception of the outer edge of said bead, as shown. The sockets orlifters G maybe formed with aproj ectin g screw, if desired, at thepoint 8, where the separate screw is applied. When they are made asshown in the drawings only two or three turns of screw-thread would benecessary to sufficiently secure the sockets in the sash.

These lifters are only intended to be applied to weighted or balancedsashes; therefore, to raise or lower such sashes requires but Veryslight effort when there is a suitable lifter provided for theapplication of that power. A lady or child may raise or lower either theupper or lower sash when provided with my litter with the greatest easeby the application of a finger of each hand in a socket on each stile ofthe sash, while without the lifter it requires considerable of aneifort, and is always attended with more or less inconvenience. When thesashes are nicely balanced they may be readily moved with one finger bymeans of this socket. There may be any desired number applied to boththe right and left hand side of each sash, and one or more in the bottomrail of the lower sash. They are preferably made of sheet-brass andnickel-.

plated.

I am aware that sash-lifters have been applied to the lower rails ofsashes; but these have never been ofa form which would allow of the usefor which mine is, by its form, adapted.

What I claim as my invention is- As a new article of manufacture, thecircular sash lifter G constructed, with flanges turned down as shownand described, to be applied to the stiles or vertical bars of the sash,and used substantially in the manner and for the purposes set forth.

HIRAM KINGSBURY.
